<p>The method involves feeding air into a high-pressure column (11), taking a liquid product flow from a distillation column system, raising its pressure, evaporating it and extracting as a gaseous product flow, compressing and cleaning the input air. A second partial flow of the input air is compressed in second and third boosters. It involves using at least some of the mechanical energy that is created by the expansion (8) of the first partial flow (7) to drive the second booster (18).</p> |
